Pregnancy safety and defence

hey mammas and mummies to be, I have a weird question from a topic I had with my partner about going out and being safe whilst pregnant.

If a situation arises when you’re out in public and say a group of yob teenagers targets you or anyone of any age, how do you handle it? Without putting yourself and baby in harms way?

I have severe anxiety and agoraphobia, therefore I basically never ever go out alone and never go into shops/places alone. I wanted to start surprising my partner with little treats like his favourite snacks, etc. Without him knowing or seeing me do it but since I don’t go out alone or to the shops ever without him, I sort of can’t? He doesn’t want me doing it alone whilst pregnant because where I live there’s been a lot of violence against pregnant women. Since I’m alternative, green hair, piercings and the whole package, I’m even more so of a target. I’ve been victim of unfortunate terrorisation due to looks in public before and now I’m more vulnerable whilst heavily pregnant. People here don’t have consideration or kindness for pregnant women, were seen like dirt.
